Electrical Devices vs. Electronics Devices: What's the Difference?

Edited by Janet White || By Harlon Moss || Updated on October 17, 2023
Electrical devices work on electrical principles; electronics devices use semiconductors and circuits.

Key Differences

Electrical devices generally pertain to equipment working on basic electrical principles. In contrast, electronics devices are specific to items that involve complex circuitry and semiconductor technology.
While electrical devices can be as simple as a light bulb that uses electricity to emit light, electronics devices integrate components like transistors, diodes, and microchips to perform intricate tasks.
The primary function of electrical devices is typically to convert one form of energy into another, like electrical energy into heat or motion. Electronics devices, however, often process, control, or store information using electrical signals.
Electrical devices are often about power generation and distribution, like motors and generators. Meanwhile, electronics devices cater more to communication, computation, and entertainment sectors, like smartphones and computers.
The design and operation of electrical devices usually involve macroscopic components and systems. In contrast, electronics devices delve into the microscopic realm, dealing with small currents and voltages on semiconductor materials.
